“Global warming is the increase in the average temperature of the Earth’s surface” (Global Warming) . It has the effect of making the Earth’s surface warmer compared as it was the previous years. Such warming effect is also referred to as the “greenhouse effect”. Accordingly, “the global average temperature has increased about 0.7 to 1.4 degrees F (0.4 to 0.8 degrees C) since the late 1800's and many experts estimate that the average temperature will rise an additional 2.5 to 10.4 degrees F (1.4 to 5.8 degrees C) by 2100 in which, that rate of increase would be much larger than most past rates of increase” (Global Warming).
The Constitutional Rights Foundation explained how the “greenhouse effect” works: “Radiation from the Sun in short wavelengths easily pass through the Earth's atmosphere and strike the surface, which reflects much of it back as longer wavelengths” (Global Warming: What Should We Do About It?). “Instead of going back into space, the longer wavelengths are absorbed by gases in the atmosphere”. “The atmosphere reflects back to the Earth's surface a significant amount of the trapped radiation, which becomes heat”.
There are many possible causes of global warming. However, for the past several years, NASA noted “that most of the causes of global warming are man-made activities”. The “burning of fossil fuel is the top list of man – made activities that largely contribute to global warming and this occurs in automobiles, in factories, and in electric power plants that provide energy for houses and office buildings” (Global Warming). The burning of fossil fuels produces carbon dioxide (CO2), a chemical element that “slows the escape of heat into space” (Global Warming). Ramsey and Burckley said that “the amount of carbon dioxide in the air would strongly influence climate because of the ability of this gas to trap radiated heat” (p. 608 – 609). “According to the Intergovernmental Panel on Climate Change (IPCC's) report, CO2 concentrations in the atmosphere (if no measures will be adapted to mitigate its production) will double by 2100” (quoted from “Global Warming: What We Should Do About It?”). “This will cause an average increase in the global surface temperature between 3.5F and 10F”. “The rate of temperature increase during the century will very likely be greater than at any time in the last 10,000 years”.
Global warming is a very vital issue and states must deal with it seriously to moderate if not to stop it from getting worse. It is because more scientists agree that global warming has more of negative effects rather than positive ones. It could make the weather unpredictable and more damaging as it could produce rainfalls that can “increase flooding in some areas but could bring drought to some” (Global Warming). It could also make hurricanes and other tropical storms “more powerful” and in “frequent occurrence”s (Global Warming). Extreme flooding and drought could lessen food production in a high rate that could lead to extreme famine in many parts of the world.
The most dangerous thing that the global warming could bring is the melting of ice in many ice regions of the world, particularly in the West Antartica. Dangerous because according to scientists, melting of ice in these regions could cause rising of the sea level entire the world. If the sea level rise, “many coastal areas would experience flooding, erosion, a loss of wetlands, and an entry of seawater into freshwater areas” (Global Warming). “High sea levels would submerge some coastal cities, small island nations, and other inhabited regions” (Global Warming). Thus, rising of the sea level could mean loss of many lives and properties in many parts of the world.
In great recognition of these possible damages that could be brought about by global warming, the Constitutional Rights Foundation reported that “in 1997, more than 160 nations met at Kyoto, Japan, to work out a...
